Kinect in Motion - Audio and Visual Tracking by Example

Overview of this book

Kinect is a motion-sensing input device by Microsoft for the Xbox 360 video game console and Windows PCs. It provides capabilities to enhance human-machine interaction along with a zero-to-hero journey to engage the user in a multimodal interface dialog with your software solution. Kinect in Motion - Audio and Visual Tracking by Example guides you in developing more than five models you can use to capture gestures, movements, and voice spoken commands. The examples and the theory discussed provide you with the knowledge to let the user become a part of your application. Kinect in Motion - Audio and Visual Tracking by Example is a compact reference on how to master color, depth, skeleton, and audio data streams handled by Kinect for Windows.Starting with an introduction to Kinect and its characteristics, you will first be shown how to master the color data stream with no more than one page of lines of code. Learn how to manage the depth information and map them against the color ones. You will then learn how to define and manage gestures that enable the user to instruct the application simply by moving arms or any other type of natural action. Finally you will complete your journey through a multimodal interface, combining gestures with audio.The book will lead you through many detailed, real-world examples, and even guide you on how to test your application.

Chapter 4. Speech Recognition

In the previous chapter we saw how to use the Kinect sensor skeleton tracker for providing inputs to our application. In this chapter we will explicate how to use the Kinect sensor's speech recognition capability as an additional natural interface modality in our applications. Speech recognition is a powerful interface that increases the adoption of software solutions by users with disabilities. Speech recognition can be used in working environments where the user can perform his/her job or task away from a traditional workstation.

In this chapter we will cover the following topics:

  • The Kinect sensor audio stream data

  • Grammars defined by XML files and programmatically

  • How to manage the Kinect sensor beam and its angle

The Microsoft Kinect SDK setup process includes the installation of the speech recognition components.

The Kinect sensor is equipped with one array of four microphone devices.

The array of microphones can be handled using the code libraries released by...
